I'm not your...

It's no new phenomenon that hosers will use words that make others cringe while thinking themselves clever or... I don't know... hip? You know there was that guy in the 19th century who called everybody "guv'na" and everyone else was all, "Yeah, alright man, just because we're having tea together doesn't give you license to talk like an asshole." Or when you're time traveling to prevent an imminent apocalypse and you keep getting "Og no like boomstick!" and you're like, "Come on Og, all your friends are calling it a shotgun... and how about some verbs every now and then? I didn't spend all that time teaching you English so you could talk like a stereotype." I hate that!

I was reminded of this problem just this morning when a guy called me "Chief." As in, "Make it a medium, chief." He got the coffee, yeah, but he also got a glare of well-masked incredulity. The urge to return fire is fairly intense. "Enjoy the coffee, Ace!" I've come up with a way to tell if the nickname you're about to apply to a complete stranger is inappropriate. Consider if you would use the same word in the following scenarios:
1. Your eight year-old gets his first hit in T-Ball
2. Your 94 year-old relative is having war flashbacks (you're not being an asshole or anything; you're just helping him cope)
3. A fellow trucker gives you a thumbs up when you drive past
4. When playing kickball with friends, somebody completely whiffs on a slow pitch ("Good hustle though, Tiger!")
5. You're trying to kill the mood when your partner wants sex and you don't
6. You're naming your new puppy

Here's a rough list of offending names:
-Chief*
-Buddy*
-Friend*
-Brotha
-Pal*
-Partner*
-Cowboy
-Ace
-Tiger
-Sport*
-Champ*
-Li'l man*
-Scooter (actually this was my parents' nickname for me as a child)
-Dude-a-rino
-Boy*
-Playa*
-Killa
-Rockstar*
-Superstar
-Pimp
-Chump
-Bra (there was a plumber in Hillsborough who used this word at least once in every sentence)
*I have been called this by customers or maintenance workers, in earnest

Nicknames are not the end of it, sadly.
-"Can I get that latte with a smirch of vanilla?" I can only guess that was meant to be a cross between "pinch" and "smidgen."
-"Does that come with a squirt of chocolate?" Sure, let me just run to the back here...
-"I want it with an extra pump of caramel." Don't we all.
-"Frozen mocha with froyo." I now call this the Froyo Fromo (patent pending).
-"Latte. Super flat, super fly." Okay, the woman who says this actually pulls it off. If anyone else tried it they'd be a tool faster than I could smile awkwardly at them.

As usual, I'll request you put your own examples in the comments. Then, as per usual, no comments will appear. Good on ya, mate!
